That's all well and good but it bears mentioning that in Japan Famitsu is synonymous with gaming, they are a 25 year old gaming magazine and have significant influence on the worldwide games industry and how it perceives games, when Famitsu gives a game a 40/40, Japanese developers drop what they are doing and take notice.
This isn't your typical Xbox magazine or even PC gamer, its much older and much more influential, not to mention that Skyrim is the FIRST western-made game to ever get that score there. Again, in 25 years of game reviews across every platform ever released. Famitsu is essentially saying that Skyrim is the best western game they've ever played since the inception of video gaming.
Yeah this giant boner you have for this magazine doesnt mean its important. Famitsu doesnt speak for the entire gaming community, and until they do they are just an opinion based magazine. No more reliable then Gamefaqs or IGN or any of those sites. They say their opinion and no matter how highly its held its just that, someone elses opinion. And the day I let someone elses opinion change the way I think about something is the day I blow my brains out. I can think for myself, thank you very much.
So like I said, "Hoorah." they gave the game a great score, that doesnt mean its the best blah de blah de blah. It means some Japanese magazine likes it, end story. Not pop the champagne the troops are coming home type excitement or anything.
TL;DL version: Its some dumb magazine, who cares?
